所有家用电器在电机运行中，均产生不同程度的谐波电压和电流，使电动机在非正弦电压、电流下运行。高次谐波会引起电动机定子铜耗、转子铜（铝）耗、铁耗及附加损耗的增加，为显著的是转子铜（铝）耗。因为普通的交流异步电动机是以接近于基波频率所对应的同步转速旋转的，因此，高次谐波电压以较大的转差切割转子导条后，便会产生很大的转子损耗。除此之外，还需考虑因集肤效应所产生的附加铜耗。这些损耗都会使电动机额外发热，效率降低，输出功率减小，但如果使用变频电机，其能耗能减少20%-30%左右。
ABB变频电机谐波电磁噪声与震动更小
普通异步电动机由于电磁、机械、通风等因素所引起的震动和噪声变的更加复杂。变频电源中含有的各次时间谐波与电动机电磁部分的固有空间谐波相互干涉，形成电磁激振力。当电磁力波的频率和电动机机体的固有振动频率一致或接近时，将产生共振现象，从而加大噪声。由于电动机工作频率范围宽，转速变化范围大，电磁力波的频率很难避开电动机的各构件的固有震动频率。但是变频电机就可以有效解决这些问题。
